It is worth noting that there were actually two passes at this location. The lower pass was more prone to being blocked by Orcs, hence most travellers used the higher pass outside of those rare occasions when the Orcs were suppressed.

Names

The High Pass was also known as the Pass of Imladris. In Sindarin, the pass was called Cirith Forn en Andrath ("the high-climbing pass of the north"); cirith + forn + andrath).[4][5]
